I am trying to program a future system which would buy one
contract at first signal, an additional contract if the trend starts developing  and
several more contracts to a maximum of 4 contracts. Each new contract would be
entered when the price moves up by ½ ATR (20). 
 
Let’s say I have a code something like this …..
 
-----------------------------------------------------------
 
Positionsize=margindeposit=1; // this is for original one contract test
 
 
Tick = 1; //YM tick
Buyprice = ema (6) + Tick;
 
Applystop ((stopTypeLoss,stopModePoint,1.5 * round(MA(ATR(1),20)),0,False,0);
 
buy = cross (ema (6), ema (13));
 
 
Thank you for any help.
